Your answer is C - 50.
Hope this helps.
Step-by-step explanation:
x + 149° = 180° {Being linear pair }
x = 180° - 149°
x = 31°
Hope it will help :)❤
remember that to put a number in scientific notation is necessary to have the first digit of the number different to 0, so

to calculate the order of magnitude, if the number is greater than 3.16, we assume it as a 10, so in this case as 7.654 > 3.16 we get that the order is

So the order is 10^-3
Answer$33.60
Step-by-step explanation:
First I added 23 and 6 to get $29
Then I figured out that 20 percent of 23 was 4.6 and added that to 29.
I came out with an answer of 33 dollar and sixty cents.
Step-by-step explanation:

Swap the sides of the equation :
⤑ 
We want to remove the 17.56 first.
Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :
⤑ 
Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.
⤑ 
Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.
⤑ 
Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

Hope I helped ! ♡
Have a wonderful day / night ! ツ
